Coating Rod for molding

The coating applicator rod controls the transfer amount of coating through precisely machined grooves or ridges on the metal rod surface, forming a uniform wet film on the substrate. It is used in laboratories to simulate the blade coating process and to test the leveling, hiding power, and other properties of coatings. It is suitable for thin-layer coating tests such as ink printing and paper coating.
Selection
When selecting, consider matching the substrate roughness to the rod diameter, aligning the coating thickness with the groove depth, and ensuring the paint viscosity is compatible with the rod material. Stainless steel rods are resistant to solvents, tungsten steel rods are wear-resistant, and plastic rods prevent substrate scratching. Ensure the rod length covers the sample width and clean it promptly after use to maintain the integrity of the groove shape.

The oral dissolving film is uniformly coated by a film applicator and then dried and formed.
Oral dissolving films are prepared by a coating mechanism, where a liquid containing film-forming materials is uniformly applied onto a substrate, followed by drying to remove the solvent and form a solid film.
The role of a bending stiffness tester in evaluating the rigidity and formability of cardboard.
The bending stiffness tester evaluates the rigidity and formability of cardboard by measuring its resistance to bending deformation. Based on the beam bending theory, it is tested under standard conditions, providing bending stiffness value as the core indicator.
The working principle of laboratory wire rod coaters and methods for controlling coating thickness
The laboratory wire rod coater is a precision instrument used to prepare uniform, thickness-controllable wet film coatings on substrate surfaces. Its core components include a coating rod, a flat coating platform, clamps for securing the substrate, and a mechanical system that drives the coating rod to move at a constant speed.
The difference between a wire-wound rod coater and an extrusion coating rod
This article primarily compares the technical differences between wire-wound and extrusion coating rods. Although they are interchangeable in most scenarios, there are subtle variations in liquid loading capacity due to their distinct groove principles.
